4 Claims. or. 155-106) This invention relates t o articles of furniture and more particularly to articles of reposefor supporting the-body of a person wherein a back-rest seat and leg-rest are movable in a predetermined relationship relative 'to-a sup- Anobject of theinvention is to provide an article of repose of above described type with an advantageous mechanism for controlling the-movementsof the leg-rest independence on movements of the back-rest.

[,Anotherobject'of the invention is to improve on the construction of articles of repose as.now customarily made. r Other objects and structural details of the invention will be apparent from the following description when read in conjunction .with the accompanying drawings forming part of this specification, wherein:

Fig. 1 is a side elevational view o'f'an adjustable reclining chair accordingto the invention, a portion of a side wall being broken away,

tentO Fig. 2 is a similar sideelevational view of thechair shown in Fig; 1, wherein however the movable members of an armchair according to the invention, a portion of a side wall being broken away,

"Fig. 4 is a similar side elevational view' of the arm chair shown in Fig. 3, wherein however the movable members of thechair are in the extreme reclined position, a Fig. 5 is a side'elevational view of a further embodi ment of an armchair according to the invention, apor- Fig.;6 is a similar side elevational view of the chair shown 'inFig'. '5, wherein however the movable members of the chair arein'the extreme reclined position.

' Referring-now. to Figs. 1 and 2,10 generally indicates a support having suitably connected sidewalls l2 and 14 and a rear wall 16.

Ab'ack-rest generallyindicated by 18 is swingably mounted on the support 10 at 20." An extension 22 rigid with the back-rest ls projects downwardly beyond th'e' pivot20.-" f A seati24 is swingably mounted on the support 10 at 2,978,010 Patented Apr. 4, 1961 A first connecting link 50 is pivoted to the first arm 26 at 52 and to the seats 24 at 54. Thus movements of the seat 24 are controlled by said first connecting link 50 in dependence on movements of the first arm 26. If desired however, said connecting link 50 may be replaced by diiferent means for controlling movements of the seat 24 in dependence on movements of the first arm 26.

The rear end of a second connecting link 56 is pivoted to the downwardextension 22 of the back-rest 18 at 58. The front end of said second connecting link 56 is pivoted to the'first arm 26 at 36 in coaxial alignment with the pivotal connection between the first arm 26 and the link 34. If desired, however, the pivotal connection between the second connecting link 56 and the first arm 26 may be spaced from the pivotal connection between the first arm 26 and the link 34. Thus, the second connecting link 56 controls the movements of the first arm 26 and thereby the movements of the .seat 24 and of the legrest 40 in dependence on movements of the back-rest 18.

The relative movements of the back-rest 18, seat 24 and leg-rest 4 0 are determined by the constrained linkage described above. The sitting position is shown in Fig. 1 and the extreme reclined position is shown in Fig.2. a 1: A

According to the embodiment shown in Figs. 3 and 4, the arrangement ofthe back-rest 118, the seat 124, the leg-rest 140'and the links or arms 130, 144, 126, 150 and 134' relativeto each'other and relative to the support 110 respectively'is the same as in the embodiment described above in connection with Figs. 1 and 2. How ever accordingto Figs.-3 and 4 the second connecting link 156 is pivoted at one of its ends to the'downward extension 122 of the back-rest 118 and at its other end to the second arm 130 at 160. Upon a rocking movement of the back-rest 118 from the upright position shown in Fig; 3 into the reclined position shown in Fig. 4, the constrained'linkage 156, 130, 144, 126, 150 and 134 causes a movement of the leg-rest 140 from the position shown in Fig. 3 into the position shown inFig. 4.

According to the embodiment shown in Figs. 5 and 20 in coaxialalignment; with the pivotaLconnection between the back-rest 18 and the support 10..

'On each side of the chair 'a' firstarm 26 is swingably 34 is pivoted at 38 to the upper portion of a leg-rest 40.

Thelower portion of said leg-rest 40 is pivoted at 42 to the front end of a curved link 44. An intermediate point of said curved link 44 is pivoted at 46 to the lower end of i the first arm 26. The rear end of the curved link 44 is pivotedat 48 to the lower end of the second arm 30.

other so as to form a unit generally indicated by 262. Said unit 262 is swingably mounted on the support 210 at264. 1 .1

Again a first arm 226 and a second arm 230 are swingably mounted on the support 210 at spaced points 228 and 232 respectively. Furthermore, again the leg-rest 240 is pivoted at 238 to one end of a link 234, the other end of which is pivoted to the first arm 226 at 236. The lower portion of the leg-rest 240 is pivoted at 242 to the front end of the curved link 244, which is pivotally connected with the first arm 226 and the second arm 230 at the spaced points 246 and 248. l

The control of the movements of the linkage 230, 244, 226, 234, 240 in dependence on the rocking movements of the unit 262 however is obtained by different means. According to Fig. 5 the lower end of a downward extension 266 of the unit 262 is pivoted at 268 to one end of a link 270, the other end of which is pivoted at 272 to a thirdarm 274 swingably mounted on the support 210 at 276. The lower end of said third arm 274' is pivoted at 278 to one end of a link 280, the other end. of which is pivoted to the first arm 226 at 282. A rocking movement of the unit 262 around its pivot 264 from the sitting position shown in Fig. 5 into the extreme reclined position'shown in Fig. 6 will cause an upward and forward propelling of the leg-rest 240 from the position shown in Fig. 5 into the position shown in Fig. 6 by means of the link, mechanism described above.

The preferred embodiments. of the invention have is for the purpose of illustration and that various changes in shape, proportion of parts, as well as the substitution of equivalent elements for those .herein shown and described, may be made without departing from the spirit and scope of the invention as, setforth in the appended claims. 7 y
